MYP: Biology 9th Grade (Final Exams)

Basically review cards for MYP: biology   (Ib biology for freshman)  My finals are tomorrow and these cards are basically everything that are going to be on the test...good luck! BTW, the definition opf organelless has where they are located and if they are in the plant/animal cell

114 cards   |   Total Attempts: 188
  

Cards In This Set

Front Back
Nuclear envelope w/ pores.plant&animal nucleus
A double membrane that surrounds and contains nuclear material. Nuclear pores allowmaterials to leave the nucleus into the cytoplasm of the cell.
NucleolusBoth .Nucleus
.Made up of chromatin. It assembles ribosomes.
Chromosome/ ChromatinBoth Nucleus
Store genetic information (DNA). Chromatin is DNA wound around protein spools, while chromosomes are tightly coiled chromatin during cell division.
Mitochondria “Powerhouse” BothCytoplasm
Double-membrane organelle... the site of cellular respiration in the cell. (cellular respiration breaks down glucose to release energy)
•Endoplasmic Reticulum “Internal transport system” Both .Cytoplasm
Transports material throughout cell.ser manufactures lipids/breaks down toxic substances.RER. important making of proteins due to ribosomes.
•Golgi apparatus “Packaging Plant”
Both Cytoplasm.Made up of flattened membrane sacs. Modifies and packages proteins and other substance.
Chloroplast
Plants.Cytoplasm.(contains chlorophyll), .Site of photosynthesis in a plant cell. 1st of 3 plastids.
Amyloplast/ Leucoplast
Plants.Cytoplasm.2nd of 3 types of plastids found in plant cells. They store amylose (starch).
Chromoplast
Plants.Cytoplasm.3rd of 3 types of plastids, it stores accessory pigments in plant cells.
Vacuoles/Vesicles
Both .Cytoplasm.Vacuoles/vesicles are storage compartments of the cell. They can contain food, proteins, waste…etc…
Lysosomes
Animal.Cytoplasm.Produced by the Golgi apparatus, contain digestive enzymes used to breakdown food or worn out cell parts.
Microtubules/ Microfilaments
Both .Cytoplasm.Protein fibers that make up the cytoskeleton.Microtubules are hollow tubes, while microfilaments are more thread-like.
Centrioles
Animal.Cytoplasm.Made up of 9 groups of 3 microtubules. They produce the spindle fibers that separate chromosomes during cell division.
Cell Wall
Plant.Boundary.Made up of proteins and cellulose, it provides support and protection to a plant cell. It gives the cell its shape..
Plasma Membrane
Both.Boundary.Made up of a bilayer of phospholipids with proteins embedded. Maintains homeostasis by regulating what enters and leaves the cell.
